I think a configure check is the simplest solution available.  If you
don't want to pollute your source code with #ifdef's, you could have
configure define those two symbols to 0 if they aren't defined by
gnutls.h.  I usually want to make the core code look good for the
latest-and-greatest features, and work around missing functionality in
earlier releases through some replacement stuff in configure.
